Description
~ 3~35~j The invention relates to a roofing element9 in particular a concrete roofing panel, at whose underside extend a suspension ledge and a base rib, while at least two cross ribs of lesser th;ckness than the base rib extend in the covering or overlapping region next to the base rib and parallel thereto, while the basic surface of the base rib extends parallel in relation to the outer surface of the roofing element.
Roofing elements of this type are known, for instance, from AT-PS
278321.The sealing behavior and the support of such roofing elements on a roofing element disposed underneath is not optimal, however, and moisture and wind can penetrate.
It is the object of the invention to form roofing elements of this type in such a manner that they assure the tightest possible sealing against penetrating moisture and drafts in the finished roof.
According to the invention, this ;s achieved in a roofing element of the type initially mentioned by providing, so as to increase the tight-ness of the roofing element, for the thickness of the roofing element of optionally S- or wave-shaped cross section, to be slightly less, up to 6 percent at the most, in the apex of the cross rib farthest removed from the base rib than the thickness of the roofing element in the base rib, and by providing for further cross ribs disposed between the base rib and the cross rib farthest removed from the base rib to be of lesser height than the cross rib Farthest removed from the base rib.
The cross rib farthest removed from the base rib, which is only slightly shorter than the base rib, prevents any riding up, but at the same time creates a space between itself and the~base rib which is available as a sw1rl chamber for penetrating air streams, s~ that penetrating air streams are calmed down and penetrating moisture can run off without being influenced hy capillarity due to the inclination of , the roof on the respective lower or overlapped roofing element.
The pressure of the penetrating air is reduced and a contro11ed pressure compensation between the swirl chamber and the interior of the roof or the space below the roofing is possible. The forming of the further cross rib(s) with lesser height than the cross rib farthest removed from the base rib improves the effect of the swirl chamber and thus the sealing effect between the roofing elements in the overlapping region. Preferred is a thickness of the roofing element in the apex of the further cross ribs disposed between the base rib and the cross rib farthest removed from it of about 8 to 16 percent, preferably about 10 to 12 percent, less than the thick-ness of the roofing elernent at the base rib.
The f10wing conditions are further improved in respect of sealing and minimization of drafts penetrating into the ;nterior of the roof if the thickness of the roofing element above the bottom of the grooves between the base rib and the further cross ribs and between these and the cross rib farthest removed from the base rib is equal.
The overa~ result is a roofing element of optimal sealing effect which is simple to produce and stable.
The invention is explained by means of an exemplary embodiment under~reference to the acco~panying drawing.
The drawing shows two roofing elements 3 in the overlapping region in section. In the present case, the roofing elements are of S-shape :
or wave-shape in cross section (vertical to the drawing plane). On a roof 1, there is a lattice 2 onto which the roofing elements 3 are hoDked by means of a suspension ledge 7, so~that roofing elements 3 wh;ch are hooked~cnto a lattice positioned higher rest on~roofing elements 3 of a row underneath with their overlapping or base region. The base region of a roofing element 3 according to the invention is provided with a ' ~L~ 9 5~j base r;b 4 having a basic surface 11 extending in sections parallel to the longitudinal extension or the undulation parallel to the outer surface 12 of the roofing element. Adjacent to the base rib 4, with interposed grooves 13 and 14, is a further cross rib 6 and a cross rib 5 farthest removed from the base rib 4.It is provided for the thickness 8 of the roofing element 3 measured in the apex of the cross rib 5 farthest removed from the base rib to be slightly, up to 6 per-cent at the most, preferably 2 to 4 percent, less than the height of the front face 10 or the thickness of the base rib 4.
The thickness 9 of the further cross rib 6 disposed between the base rib 4 and the cross rib 5 farthest removed from the base rib 4 is about 8 to 16 percent, preferably about 10 to 12 percent, less than the height of the front face 10 or the thickness of the base rib 4.
The thickness of the roofing element in the bottoms of the grooves 13 and 14 is mutually equal.
The base rib 4 and the cross ribs S and 6 follow the undulation or the S-shaped form of the roofing element and are proYided with the features according to the invention over their entire extensions.
On principle, it is possible to provide one or more further cross ribs outside of the cross rib 5 farthest removed from the base rib 4 in the overlapping region or to provide more than one further cross rib 6 between the base rib 4 and the cross rib 5 farthest removed from the base;rib 4.
The~roofing panels can have cross sections of S-shape or wave form, they can have straight or curved sections or be provided exclusively with straight sections or be of linear shape.
Roofing elements of this type are known, for instance, from AT-PS
278321.The sealing behavior and the support of such roofing elements on a roofing element disposed underneath is not optimal, however, and moisture and wind can penetrate.
It is the object of the invention to form roofing elements of this type in such a manner that they assure the tightest possible sealing against penetrating moisture and drafts in the finished roof.
According to the invention, this ;s achieved in a roofing element of the type initially mentioned by providing, so as to increase the tight-ness of the roofing element, for the thickness of the roofing element of optionally S- or wave-shaped cross section, to be slightly less, up to 6 percent at the most, in the apex of the cross rib farthest removed from the base rib than the thickness of the roofing element in the base rib, and by providing for further cross ribs disposed between the base rib and the cross rib farthest removed from the base rib to be of lesser height than the cross rib Farthest removed from the base rib.
The cross rib farthest removed from the base rib, which is only slightly shorter than the base rib, prevents any riding up, but at the same time creates a space between itself and the~base rib which is available as a sw1rl chamber for penetrating air streams, s~ that penetrating air streams are calmed down and penetrating moisture can run off without being influenced hy capillarity due to the inclination of , the roof on the respective lower or overlapped roofing element.
The pressure of the penetrating air is reduced and a contro11ed pressure compensation between the swirl chamber and the interior of the roof or the space below the roofing is possible. The forming of the further cross rib(s) with lesser height than the cross rib farthest removed from the base rib improves the effect of the swirl chamber and thus the sealing effect between the roofing elements in the overlapping region. Preferred is a thickness of the roofing element in the apex of the further cross ribs disposed between the base rib and the cross rib farthest removed from it of about 8 to 16 percent, preferably about 10 to 12 percent, less than the thick-ness of the roofing elernent at the base rib.
The f10wing conditions are further improved in respect of sealing and minimization of drafts penetrating into the ;nterior of the roof if the thickness of the roofing element above the bottom of the grooves between the base rib and the further cross ribs and between these and the cross rib farthest removed from the base rib is equal.
The overa~ result is a roofing element of optimal sealing effect which is simple to produce and stable.
The invention is explained by means of an exemplary embodiment under~reference to the acco~panying drawing.
The drawing shows two roofing elements 3 in the overlapping region in section. In the present case, the roofing elements are of S-shape :
or wave-shape in cross section (vertical to the drawing plane). On a roof 1, there is a lattice 2 onto which the roofing elements 3 are hoDked by means of a suspension ledge 7, so~that roofing elements 3 wh;ch are hooked~cnto a lattice positioned higher rest on~roofing elements 3 of a row underneath with their overlapping or base region. The base region of a roofing element 3 according to the invention is provided with a ' ~L~ 9 5~j base r;b 4 having a basic surface 11 extending in sections parallel to the longitudinal extension or the undulation parallel to the outer surface 12 of the roofing element. Adjacent to the base rib 4, with interposed grooves 13 and 14, is a further cross rib 6 and a cross rib 5 farthest removed from the base rib 4.It is provided for the thickness 8 of the roofing element 3 measured in the apex of the cross rib 5 farthest removed from the base rib to be slightly, up to 6 per-cent at the most, preferably 2 to 4 percent, less than the height of the front face 10 or the thickness of the base rib 4.
The thickness 9 of the further cross rib 6 disposed between the base rib 4 and the cross rib 5 farthest removed from the base rib 4 is about 8 to 16 percent, preferably about 10 to 12 percent, less than the height of the front face 10 or the thickness of the base rib 4.
The thickness of the roofing element in the bottoms of the grooves 13 and 14 is mutually equal.
The base rib 4 and the cross ribs S and 6 follow the undulation or the S-shaped form of the roofing element and are proYided with the features according to the invention over their entire extensions.
On principle, it is possible to provide one or more further cross ribs outside of the cross rib 5 farthest removed from the base rib 4 in the overlapping region or to provide more than one further cross rib 6 between the base rib 4 and the cross rib 5 farthest removed from the base;rib 4.
The~roofing panels can have cross sections of S-shape or wave form, they can have straight or curved sections or be provided exclusively with straight sections or be of linear shape.
